Don't think that if your heart rate falls below 60 that something is wrong. It is not uncommon while at rest, to have your HR dip below 60. Some people have rates that drop into the 30'3&40's while sleeping. Our heart rates will fluctuate which, for most, is a normal variable.on't think that if your heart rate falls below 60 that something is wrong.

GPS Receivers. Any navigation solution provided by a GNSS Receiver is based on the computation of its distance to a set of satellites, by means of extracting the propagation time of the incoming signals traveling through space at the speed of light, according to the satellite and receiver local clocks.
Most modern electronic ignitions use one of three types of sensors in the distributor (or crank sensor). They use either a variable reluctor sensor, a hall sensor, or an optical sensor. Older engines might use mechanical contact points. The GM HEI modules are designed to work with variable reluctor sensors.
